Answer to Problem 88RE
The Dot product
Explanation of Solution
Given information:
The vectors:
Formula used:
The dot product of the vectors are solved by the formula:
The formula for finding the angle between two vectors are:
The formula to find the magnitude of a vector is as:
Calculation:
Consider the vectors:
First Take a dot product of
Now apply the Dot product formula of the matrix:
Now apply the formula to find the angle between the both vectors
Here first find the value of magnitude of
Now find the value of magnitude of
Now apply the values of magnitude of the both vectors
Apply the values in the formula:
Thus, The Dot product
